The Workforce AI Index · Industrials
Delta Air Lines (DAL)
An airline read as one pattern. Read October 1, 2026 from the annual report for the period ending 2025-12-31, filed 2026-02-11. Ranked 12 of the 28 Industrials companies read so far, by the share within reach now: the sector.
An airline whose filing states a full-time equivalent total and a union share and describes one business, so the workforce is read almost entirely into the scheduled air transportation pattern.
The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.
What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 17% now, 20% at the end of 2027, 21% at the end of 2028, 21% at the end of 2030. By the patterns, the work is about 21% desk work, 26% people work and 52% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 78% of the working time stays with people (conversation, in-person and hands-on work), 15% becomes checking a model's work and 6% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
Headcount
103,000 employees as of 2025-12-31 (full-time equivalent). The filing does not state a count by country.
The filing: “As of December 31, 2025, we had approximately 103,000 full-time equivalent employees, approximately 20% of whom were represented by unions.”
The workforce as industry patterns
| Pattern | Share | Reason, from the filing |
|---|---|---|
| Scheduled Air Transportation | 95% | By (c): the filing states one full-time equivalent total and describes one business, a scheduled passenger airline with its flight, ground, maintenance and customer operations, so nearly the whole workforce is read into the scheduled air transportation pattern; no count by group is stated. |
| Support Activities for Air Transportation | 5% | By (c): the filing describes maintenance, repair and overhaul services performed for other operators by its technical operations business, with no stated count, so a small share is read into the air transportation support pattern by description. |
What the filing says about the workforce: Approximately 103,000 full-time equivalent employees, about 20% union-represented; the filing speaks of more than 100,000 employees and of its Safety Management System as central to its operations.

The estimates are the site's industry estimates weighted by those shares, from O*NET tasks with estimated lengths and METR's measurements of how long a task AI models can finish. A company can write to info@stratussc.com to have its reading checked against its filing.
